I recently pre-wired my home for two hdmi extenders that use two Cat5e cables a piece to extend the inputs to my amp. The first hdmi extender works fine, but when I hooked up my Cat5 tester the other pair of Cat5's pin number 6 shows no connectivity. I replaced the RJ 45's at each end of the cable and tested them independent of any other component that could fail other than the cable. Needless to say, that HDMI extender will not work. I pulled the extender apart and it appears to use every pin from both Cat5's on the attached circuit board. The Cat 5's are in a location that is not easy to access, which is why I pre-wired them. Anyone have any suggestions on trouble shooting this? Like with 802.3, are their pins in the extenders that don't get used that I can swap no 6 with? Any help would be great. The extender I am using is a Monoprice unit Product ID: 6532. Sorry, I would post a link but AVS doesn't think I am cool enough yet. (I dont have 3 points.)
